태양광 발전용 SEPIC-Flyback 컨버터

In this paper, we proposed a design photovoltaic generation systems with SEPIC-Flyback converter. The SEPIC-Flyback converter is operated to SEPIC converter the state tum-on of the switch and the state tum-off the switch is operated Flyback converter. Therefore application rate of the core increases and voltage stress of switch and transformer decreases with active clamp operation. Also we performed MPPT(Maximum Power Point Tracking) control for efficient working of photovoltaic power generation system.
